Aug 14, 2018 · code taken from https://www.c-sharpcorner.com/article/splitting-pdf-file-in-c-sharp-using-itextsharp/ i got a routine which add page number. try { //everything passes our tests, so make the COM call int acctId = base.AccountLookup(searchArg, (int)validSearchType); //check the result if (acctId == 0) { throw new ApplicationException( String.Format("Account not found for {0} {1}", searchType, searchArg)); } //retrieve the current balance for the account result = base.GetCurrentBalance(acctId); } catch (Exception e) { throw new ApplicationException( "Exception thrown calling COM method", e); } return result; } After executing the private validation methods, the code calls the COM AccountLookup method. Notice that we didn t need to create an instance of the COM RCW here. Remember that our class is the RCW since it is our base class. If the search is successful, we call the COM GetCurrentBalance method and return the currency result to the caller. Here is the code to test this new class: /// <summary> /// Test of an extended COM RCS class /// </summary> class ExtendComTest { static void Main(string[] args) { //create an instance of the extended RCW ExtendedComClass comObj = new ExtendedComClass(); decimal acctBal = 0m; acctBal = comObj.AccountBalance( "first last", SearchType.Name); Console.WriteLine("Balance by Name: {0}", acctBal); acctBal = comObj.AccountBalance( "123-45-6789", SearchType.TaxId); 7 8 9 Console.WriteLine("Balance by Tax Id: {0}", acctBal); acctBal = comObj.AccountBalance( "1 main street", SearchType.Address); Console.WriteLine("Balance by Address: {0}", acctBal); //wait for input Console.WriteLine("Press any key to exit"); Console.Read(); } } Notice that we create an instance of our new extended class, not the original RCW. The results of this test look like this: Balance by Name: 5432.11 Balance by Tax Id: 1.01 Balance by Address: 5.95 Press any key to exit Here is the same functionality implemented in Visual Basic .NET (VB.NET) instead of C#: Imports System Imports System.Runtime.InteropServices Imports System.Text.RegularExpressions Imports Interop.DniExtendComVB ''' <summary> ''' Define search types '''</summary> Public Enum SearchType Unknown = 0 Name = 1 TaxId = 2 Address = 3 End Enum ''' <summary> ''' Extend a COM RCW ''' </summary> Public Class ExtendedComClass Inherits DniExtendComVBObjClass 'the RCW Public Function AccountBalance(ByVal searchArg As String, _ ByVal searchType As SearchType) As Decimal Dim result As Decimal = 0 2 15 16 'validate the requested search type Dim validSearchType As SearchType _ = ValidateSearchType(searchType) 'validate the search argument based on the search type ValidateSearchArgument(validSearchType, searchArg) Try 'everything passes our tests, so make the COM call Dim acctId As Integer _ = MyBase.AccountLookup(searchArg, validSearchType) 'check the result If acctId = 0 Then Throw New ApplicationException( _ String.Format("Account not found for {0} {1}", _ searchType, searchArg)) End If 'retrieve the current balance for the account result = MyBase.GetCurrentBalance(acctId) Catch ex As Exception Throw New ApplicationException( _ "Exception thrown calling COM method", ex) End Try Return result End Function ''' <summary> ''' Validate the search type ''' </summary> ''' <param name="searchType"></param> ''' <returns></returns> Private Function ValidateSearchType(ByVal searchType As SearchType) _ As SearchType Dim validSearchType As SearchType _ = ExtendComVB.SearchType.Unknown If [Enum].IsDefined(GetType(SearchType), searchType) Then validSearchType = searchType Else Throw New ApplicationException(String.Format( _ "Search type of {0} is invalid", searchType)) End If Return validSearchType End Function ''' <summary> ''' Validate the search argument based on the search type. c# split pdf into images Split PDF into Multiple PDFs using a Range of Pages in C#, VB.NET
